LOSS PER SHARE
LOSS PER SHARE
Basic loss per share is computed by dividing our net loss by the weighted average number of shares outstanding during the period. Diluted loss per share is computed by dividing our net loss increased by dividends on preferred stock by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. In the periods in which their effect would be antidilutive, no effect has been given to outstanding options, warrants or convertible Preferred Stock in the diluted computation. Potentially dilutive shares issuable pursuant to the 2033 Senior Notes (defined in Note 6) were not included in the computation of net loss per share for the year ended December 31, 2014, because their inclusion would be antidilutive.
A total of 28,456,149, 32,105,859 and 26,695,436 potential shares of Common Stock have been excluded from the calculation of diluted net loss per share for the years ended December 31, 2014, 2013 and 2012, respectively, because their inclusion would be antidilutive.
During the year ended December 31, 2014, 5,787,983 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 5,392,741 shares of Common Stock. Of the 5,787,983 Common Stock options and Common Stock warrants exercised, 426 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the agreements.
During the year ended December 31, 2013, 10,881,570 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 10,732,745 shares of Common Stock. Of the 10,881,570 Common Stock options and Common Stock warrants exercised, 148,825 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the agreements.
During the year ended December 31, 2012, 1,086,361 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 1,084,982 shares of Common Stock.
